CONTROL MECHANISM.

Specification of Letters Patent.

States, residing at citizen of the United Ohio, have invented Lucas county,

new and useful Control Mechanisms,

which the following is a specification.

This invention relates to simplified positive control mechanisms.

ing position This invention has utility when embodied in speed and direction control of machines, especially applicable in connectionwith me chanical propulsion, as with motor vehicles.

Referring to the drawings:

Figure 1 is a fragmentary side elevation of an embodiment of. the invention in con-' nection' with a motor vehicle; I

Fig:2 is a fragmentary side elevation on an enlarged scale of the selector in connectbetween the shift mechanism and the actuator therefor; l

Fig. 3 is afragmen'tary plan view of the 3 pair of shift members;

Fig.4 is a side elevation of a selector cam,

showing therelative positions of the several cams thereto; Fig. 5 is afragmentaryplan vlew of the device of Fig. 1; i

Fig. 6 is a plan view of the mechanism of ig. 7 is a plan viewof the actuatlng ele ments of Fig. 2; and

Fig. 8 is a fragmentary plan vlew of the steering wheel with the se ector connected thereto.

. disposed The motor vehicle 1 is provided with the steering post 2 having the steering wheel 3 mounted thereon. Carried in the steering wheel 3 is the indicator 4 having notations which in this instanc may signify reverse, neutral, slow, intermediate and high speeds, identified by initials R, N, S, I, H. Adjacent the notations4 are position fixing seats 5 into which the pin6 of the yielding arm 7 may snap to hold the arm? in ad usted positlon-and therebyinsure" the selected rotation by the arm 7 of the rod 8. This rod 8 through the steeringpost 2 has the bevel gear 9 in mesh with thebevel gear 10 on the shaft 11 carrying the arm 12-serv1ng to reciprocate the rack bar 13 inmeshwith the pinion l t on the shaft 15 having thereon the several cams 16. y l

These cams 16 have irregular portions .17

Figs. 4, 6. It is'to benoted thereis a-pos 22 against the cam 16. The pin 22 is yieldably out of alined relation as shown-in Patented Aug. 14,1917.

tion for the set of cams 16 where no irregularity 17 occurs. This position 18, Fig. 4., determines; the neutral selector position of the selector, as at this set position down the cams 16 hold all of the dogs 19 out of con necting position. Foreach cam by the compression spring 21 to holdthe pin mounted in the dog 19 by the spring 23 held in position by the plug 24. The motor 25 is provided with the fly wheel 26 opposing which is the clutch 27 held normally in driven engagement from said fly wheel by the springs 28. The clutch member 27 has the extension29 to which is pivotally connected the foot clutch lever 30 having the fulcrum pivot 31. With the clutch in normal connecting position, the shaft" 32 is the driving member having the pinion 33 (Fig. 5) thereon. The pinion 33 is in meshwith the gear 34 on the counterv shaft 35 which carries the intermediate speed ear 36, the slow speed gear 37, and is in rivingrelation with the intermediate reverse pinion 38. The driven member or shaft 39 has thereon the gear 4L0 which may be shifted by the shiftv memberl into driven engagement from the reverse pinion 38 or slow forward actuation'from the gear 37. The gear 42 on the shaft 39 may be moved by the shift'member43to be inmesh with the intermediate speed gear 36, while the opposite shift of the member 43 directly connects the'shaft 39 to be driven from the shaft 32. l The shift mom or 41 has extensions 44,

45, provided with seats 46, 47, respectively effecting reverse andslow speed driving connection of the mechanism just described for establishing a plurality of driving relations between the driving member 32 and the driven member 39. The change speed mechanism is but a type, it being contemplated 100 by the invention hcremto effect. selection and throwing into selected driving relation of control mechanisms.

actuating means is herein shown connected 110 16, thereis a-dog 19, pivotally mounted in brackets 20 and actuated 50, 51, respectively to the foot lever 30.

Pivotally connected to the foot lever 30 is the link element 52 indicator 4;

spring 54 against the head 55 inthe relatively telescopic drum 56 of clutch 27 to be disconnected before effecting actuation of the element 58in one direction and simultaneously similarly oppositely moving by means of the intermediate pinion 59, the member 60. These elements 58, 60

have seats 61, 62, 63, 64, respectively movable into registering relation with the seats or openings 46, 50, 51, 47, of the shiftmembers d1, 43. Guides 65, 66 hold the shift members and actuating elements in sliding contact for their reciprocations. Stationary retaining keeps 67 are connected to the guide 66. These keeps 87 provide a shoulder overlapping the club head of the dogs 19, at all positions of the dog travels in their pivotal mounting on the shift member extensions 44, d8, 49, 4:5,except when the dogs have their yielding pins 22 directly below the cam shaft 15. Accordingly when the actuating elements 58,, 60, bring the shift members up to this neutral position, the cams 16 which have their regular sides down may withdraw the dogs from connecting engagement between the actuator elements and the shift members. The throwing of the clutch lever forward first brings the actuator elements to neutral position and with the actu ator elements in this travel to disconnecting position is positively drawn such shift member as may have been shifted to some driving relation. The parts are thus in disconnected relation and ready for selected driving connection at the recover actuation of the clutch lever by the dog connecting the selected actuatolr and shift member for mechanism con tro In operation, the driver of the car may make any selection within the range of the selector provided. This manual'operation may occur at any time, precaution selection, say for slow speed when normally traveling on high, or for high speed when traveling on intermediate. 'In the latter instance, when a steeprise is reached, -mere thrusting of the clutch foot lever, provides a manual actuation independent of the selection effecting the elected speed change. The setting of the selector is accomplished by moving the arm 7 to the indicated. change desired as shown by the This movement of the arm 7, rotates the cam shaft 15 to aline the cams 16 for neutral, if the shift is to mean no connection, the shift shall be to reverse, then the cam adjacent the pinion 14 is set as shown in Fig. 3 for the dog has i the second link element 57, thereby forming an extensible link which may be adjusted to permit the.

and may be even a or to aline the cams, say so that as shown in Fig. 2 and moves the shift members apart dropped past'the keep 67 through the seat 46 into the seat 61 and the actuator element 58 and the shift member 41 are connected. After this shifting action by thrusting 'of the foot lever, and the recover thereof by the action of the clutch springs 28 to bring about the selected driving connection of the mechanism, at any time the selector may be operated for any oth'erspeed change and thereafter such selector setting may be acted upon by an independent operation.

The mechanism is simple in its structure for general application to a plurality of shift members or adaptation to a plurality of speed change relations. There is no necessity for a driver of an automobile to be-' come confounded by a multiplicity of control devices in remote relations or which may require complex manipulation. Herein the actuation is simple along usual lines for definite reliable use in any emergency as .well as in usual practice.
